To all whom it may concern:

Be it known that I, SAMUEL V. REEVES, a citizen of the United States, residing at Haddonfield, county of Camden, State .of New Jersey, have invented a new and useful Hot-VVater Stove, of which the followl ing is a specification.

My present invention consists of a novel construction of a hot water stove in which the core of the water jacket is formed-in a novel manner and wherein both ends of the water j acket have the same conformation so that the water jacket is reversible end for end and may be rotatably adjusted as desired inorder to connect the jacket with the water conduits. v

It further consists of a novel water jacket having its greatest diameter at the medial point equidistant from the top and bottom,

theupper annular wall of said jacket converging upwardly from said medialfpoint and the lower annular outer wall of said jacket converging downwardly from said medial point with the inclination of said upper and lower wall with respect to the longitudinal axis of the, water jacket substantially alike and with the inner wall of the water jacket in proximity to the water conduits of greater thickness, in order to reduce to a minimum the variation in temperature of the water within the jacket due to I the cold water passing into the water jacket.

It further consists of a novel construction and arrangement of a heat conveyor and water distributer which causes the cool water being admitted to first come into contact v with a thicker wall of the water jacket.

Other novel features of construction andadvantage will hereinafter more clearlyiappear in the detailed descriptionof my'inven-. tion. r a

For the purpose of illustrating my inven-. tion, I have shown in the accompanying drawings one form thereof which is atpresent preferred by me, since the same will give in practice satisfactory and reliable'res ults,

although it is to be understood thatjthe varij ous instrumentalities of which my invention 7 consists can be'variously arranged andzorganized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein'shown anddescribed.

ported in any desired manner, for example, 1

by means of the legs 2. The upper face of the baseportionis provided with an annular groove 3 inwardly ofwhich is an annular I groove t' adaptjed to receivethe grate 5. The upper or fuelsupporting surface of the grate is preferablyjin 'alinementwith the top face ofthe baseportion j'1.' The base portion 1 is provided with a desired number of apertured ears or lugs 6, which are adapted to registerwith theape'rtured lugs or'ears 7 so-that the cylinder or water. jacket 8 may be connected with the base portion 1 by means of fastening devices 9 of any desired The bottomv face of the water jacket 8 is provided near its inner periphery with an outwardly extending flange 10 which is adapted to seat in the annular groove 3.

" Theopposite end of the waterjacket'8 has the same conformation, 'suchjend' being provided with the outwardly extending flange 11,thereby forming a shoulder 12, it being seenthatthe flange 10 at the opposite end of the jacket also forms a shoulder '13, so that the water jacket 8 may be reversed, if desired, without any 'change whatever in the construction'of the base portion 1" or the top portionlifwhich' lattenis adapted to seat on the shoulder 12 or the shoulder 13; The

water jacket 8 i's illustrated, in the present instance,"as'beingprovided with an inner cylindrical wall 15 and an outer "annular wall 16. The outer annular wall 16 has its greatest diameter'at the medial point equldistant' fromi'the top and bottom of the water jacket. The, upperannular outer wall of said jacket converges upwardly from the The upper end of the water jacket is pro- 7 vided with the apertured cars or lugs 18 which are adapted to receive fastening devices 19, which are connected with the topportion 14 in any desired manner. In the present instance-1 have shown these fastening devices as consisting of bolts passing. through apertu-red lugs or cars 32 on the top portion 14; and through the apertured l8 and provided with nuts.

If the inner wall of the water jacket is made of uniform thickness throughout, the cool water which 18 being admitted decreases the teinpertaure of the water Within'the Water j acket, and in order to overcome this,

the inner wall of the, water jacket opposite a port 20 or 21 is made thicker, as at 22, (see Fig. This increased thickness of the wall is preferably of greater diameter than the ports 20 and 21 or the conduits communicating therewith, 23 and 24, respective'ly. The portion 22 of the water jacket is the same at each end and it'is therefore believed to be unnecessary to describe in detail the construction at each end. The portion 22 of increased thickness is provided in line with a conduit, such as for example, 23,.wi-th a threaded recess 25, adapted to receive" the threaded end 26 of a heat conveyer and water spreader 27. This heat conveyer and water spreader comprises preferabl a single piece of material having the rearward threaded portion 26 and interme diate portion or flange 28, the rear face of which forms a curved surface and the forward face of which has a conical con-tour, as 29. Extending forwardly from the conical portion 29 is the cylindrical or other shaped extension 30, which is adapted to extend into one of the conduits 23 or 24. The intermediate portion 28 is provided with a series of apertures 31 therethrough.-

It will be seen that the cool water entering. through theconduit '23, for example, will be subject to the heat units radiating from the heat conveyor 27 and the Water coming into contact with the conical shaped face 29 will be spread laterally so that it will first come intocontact with the Wall of increased thicknes's, 22. This heat conveyer is adjustably carried by' the water jacket, so that the spreading action on the water may be varied as desired.

By reason of my novel construction of water jacket and the arrangement of the grate, the hottest portion of the fire is in about the middle of the water jacket where the area of the body of the water is transversely the greatest. The cooler portions of the fire' pot are at the top and at the bottom, whereby the body of water is of less transverse area, since the upper portion of the water jacket is heated by radiant heat and at the lower portion of the water jacket, there is an accumulation of ashes. By my present construction, I avoid a trapped or retarded circulation of the water which results a strained or fractured water jacket, since in my device,- the circulation is so rapid that there is but one determinate temperature in the entire water chamber, whereas in the prior art devices with which I am familiar, there are separate and distinct tem peratures of the water, the result of which tends to retard the circulation of the water.

It will be seen that the rear face of the annular flang 29 and the heat conveyor and temperature modifier 27 has the same conformation as the juxtaposed face of the wall of the water jacket, and in the form illustrated, is curved to con-form to the curvature of the thickened wall of the jacket.

The forward extension 30 of the heat conveyer and temperature modifier may extend any desired distance into the opening in the water jacketand the fitting connected therewith, so that thetemperature; of the water within the fitting will be modified before the water enters the chamber'of the water jacket. This extension 30 is preferably provided with grooves or weakened portions 33 (see Fig. 7), so that the length of this extension may be varied in accordance with conditions and requirements met with in practice. For example, if the fitting, such as 23,- forms an elbow, the extension 30 would be shorter than if a straight fitting, was employed.

It will be seen that the Water passing through the conduit or fitting 23 will pass through the apertures 31 and come into contact with the water which is in proximity to the inner wall of the water jacket which is of greatest thickness, The water will also be deflected and distributed by the conical face 29, so that the incoming water first comes into con-tact with a wall of increased thickness, theresu-lt of which is evident. It will beseen that by employing a wall of increased thickness I near the outlet of the water chamber of the jacket, an increased amount of heat is present at such point which facilitates the circulation through the water jacket. The spreadingof the water at the inlet to the water jacket may be varied by moving the conveyor 27 relatively to the inner wal l l'5v of the jacket.

Special attention is directed to the novel manner of forming the water jacket with the top and bottom faces thereof of the same conformation and with a core chamber having its greatest diameter equidistant from the end thereof, whereby the jacket may be reversed end for end and also rotatably adjusted inv order to aline the water connections. Special attention is also directed to the increased thickness of the inner wall of the water acket in proximity to thewater connection in order to prevent the deleterious cooling ofthe body of water in the water jacket. Special attention is also directed to the novel construction and arrangement ofthe heat conveyer and water spreader or distributer, sothat the heat is radiated into the incoming water and also preferably into the water which is passing from the waterchamber of the jacket. I preferably employ a heat conveyer and distributer at the upper end of the water cham- I having a chamber provlded with an inlet her, but this may be omitted at such point, if desired. 7 i

The apertured lugs 7 cated at right angles to the apertured lugs 18, -so that when the water jacket, is re versed end to end, the ports 20 and 21 will be brought into proper position for connection with the'water conduits.

It will be apparent from the foregoing that a stove constructed in accordance with my present invention will produce a maximum amount of hot water with a minimum amount of fuel and it has been found in practice that very advantageous results can be obtained with a stove of this character,

even when the fire is banked.

It will now be apparentthat I have de vised a novel and useful hot water stove,
